Self-Propelled Lawn Mower Pulls Slowly

Is your self-propelled lawn mower slowing down over time? Does it not pull up hills the way it used to? Does it take longer to cut your grass than it did?

As a self-propelled mower ages, the drive belt will begin to wear and the drive pulleys may wear as well. When this happens, it creates less friction and the drive system begins to slow down.

Eventually something has to give and the belt will either just stop making contact or it may break. The drive pulleys could also wear out to the point that they no longer grip. Then the entire drive system becomes inoperable and you are back to a push mower. And this becomes a very heavy push mower when you have to move it.

You bought a self-propelled lawn mower to help you power through the tall grass and hills in your yard, not to become a brick that you mow your lawn with!

Changing the drive belt can be easy or difficult task depending on the brand and model of self-propelled mower you have. If it looks beyond your capabilities, check out our Locations page for a self-propelled lawn mower repair shop near you.

One Drive Wheel Stopped Turning on My Self-Propelled Lawn Mower

 

Today’s self-propelled lawn mowers either have steel or plastic drive gears. The steel gears never seem to wear out but their spring loaded woodruf keys that are on the axle can rest and stick in place. When this happens, one side or both can stop working.

If you have a plastic drive gear on the wheel, it can wear out and stop pulling the drive wheel.

In either case the drive wheels will need to be removed and the drive system inspected. While you are at it, inspect the drive belt for wear. If it is loose or rides deep in the groove, it is time for a replacement.

Carefully inspect the drive gears to make sure they are not missing any teeth or are worn out. Grass clippings can also get into them and fill the grooves between the teeth. Clean them out good and replace any worn parts. Also check the drive shaft on models that use the spring and woodruf key. Clean out the slots and ensure everything is dry and free of grease and dirt.

My Self Propelled Lawn Mower Won’t Move

Are you pushing the bar in or pulling on it and the mower will either not move at all or will move very slowly?

This problem happens when the drive belt breaks, it is worn out or the transmission has broken or the wheels or their drive gears are worn out or broke. Each of these can be systematically troubleshot to determine what the problem may be.

One of the first things to try is to start the mower and raise the drive wheels off the ground and engage the drive handle. If the wheels turn, you know that the drive system is working but not well enough to pull the lawn mower. This is normally a worn out belt or the belt has come off of the pulley.

If the wheels do not move, then the transmission could be bad, the drive wheel gear slots could be worn out or the drive gears could be broken. This will require pulling the wheels off to inspect the gears on both the wheels and gears.

If they appear to be fine, then it will be time to call a Self Propelled lawn mower repair professional. Visit our locations page for an office near you.
